"Our hearts go out to this family, and to all the children and families affected by the Newtown shootings," Jepsen said in a statement. "They deserve a thoughtful and deliberate examination of the causes of this tragedy and of the appropriate public policy responses."

By law, any claim against the state must be approved by the state claims commissioner before it can move forward. The state attorney general serves as the state's defense attorney.

"The Office of the Claims Commissioner is not the appropriate venue for that important and complex discussion," Jepsen said in his statement.

"Although the investigation is still under way, we are aware of no facts or legal theory under which the state of Connecticut should be liable for causing the harms inflicted at Sandy Hook Elementary School," he said.

According to the claim, the unidentified child heard "cursing, screaming, and shooting" over the school intercom when the gunman, 20-year-old Adam Lanza, opened fire at Sandy Hook Elementary School.

Pinsky's claim said the state Board of Education, Department of Education and education commissioner failed to take appropriate steps to protect children from "foreseeable harm" and had failed to provide a "safe school setting."

Pinsky said last week that he was approached by the child's parents within a week of the shooting.
